TYPE-BAR HANGER.

SPECIFICATION forming part of Letters Patent No. 744,253, dated November17, 1903.

Application filed April 14, 1903. 'Serial'llo. 152,574. (No model.)

To all whom it may concern:

Be it known that I, CHARLES SPIRO, a citizen of the United States,residing at New York, in the county ofrNew York, State of New York, haveinvented certain new and useful Improvements in Type-Bar Hangers,

of which the following is a specification, reference being had thereinto the accompanying drawings.

This invention relates to type-bar hangers for type-writers, andparticularly to a structure thereof adapted to be formed principally bymachine-work,thus reducing to a minimum the hand labor required thereonand the consequent cost of production, while the finished product isrendered more efficient in use.

, Heretofore in this art it has been common to cut or saw from a bar ofmetal a blank from which the bracket which in connection with the pivotforms the type-bar hanger and then bore the pivoting-lugs of saidbracket, which are required to be subsequently countersunk upon theirinner faces, thus requiring a great deal of hand-work in the productionof the article.

stamped or cut blank, which is subsequently die-pressed into shape, andan aperture of even diameter simultaneously bored through,

with lugs adapted to pass through the type-- bar and be normally securedtherewith,while the pivot is journaled at the opposite ends inadjustable sockets, which are countersunk to form the bearing-points.

Other and further objects and advantages of the invention will behereinafter set forth, and the novel features thereof defined by theappended claims.

In the drawings, Figure 1 is an elevation, with parts in section, of thetype-bar in printing position; Fig. 2, an elevation of the blank fromwhich the hanger-bracket is formed; Fig. 3, a similar view of this blankafter being die-pressed; Fig. 4, a like view of the bracket in itscompleted condition. Fig. 5 is an elevation of the blank from which thepivot and connecting'plate are formed; Fig.

The present invention contem-' plates the formation of this bracket froma 6, a similar view of this blank when diepressed into shape; Fig. 7, anelevation of one end of the type-bar; Fig. 8, a similar view showing thepivot and connecting-plate applied thereto, and Fig. 9 is a verticalsection through the assembled parts forming the hanger.

Like letters of reference refer to like parts in the several figures ofthe drawings.

The letter A designates a type-bar, which may be of any desiredconstruction and is provided at its free end with a type A, adapted tocooperate with a platen A as indicated by dotted lines in Fig. 1, whilethe opposite end of this bar is pivotally mounted in the hanger B,secured to a fixed support B for instance, the segment of a type-writerframe. The type-bar is also provided with the usual ligament A forconnection with the key-levers in the usual manner.

The bracket, which is secured to the support B is'formed from a blank ofsheet metal by cutting or stamping same therefrom, and this blank issubstantially of the shape shown in Fig. 2 when so out. In this figurethe body B of the bracket is provided at opposite ends upon one facethereof with projecting portions 13 and upon the opposite face with acentral shank-portion B The blank is then placed in a suitable die-pressand the projecting portions B formed by pressure into the circularpivoting-lugs B while the shank B is pressed into a substantially curvedform, as shown at B in Fig. 3, and each of the pivotingdugs is bored ordrilled with an aperture B of equal diameter throughout, which drillingis performed at a single operation,

thus assuring perfect alinement of the aper" tures. The blank thuspressed is now in condition for finishing, and the only further workrequired is the interior threading of the lugs B to receive thebearing-screws O and the threading of the shank B to receive the holdingnut G, as shown in Fig. 4., when the bracket is ready to receive thepivot. These screws 0 are provided with a central aperture 0 adapted topermit the oiling of the bearing and also to allow a passage for theegress of any grit or dirt which may work its way therein, while theinnerend of each screw is countersunk, as shown at 0 so as to have aconvex curved bearing-wall adapted to engage the bearing of the pivot tobe hereinafter described. The pivot is formed by stamping or cuttingfrom material a blank of sheet metal substantially of the shape shown inFig. 5, which comprises a T-shape structure having a pivot-bar D and alateral plate or bar D at one side of the longitudinal center of thebar, so as to bring the type-bar when connected to this extensionsubstantially in the center of the pivot-bar. This blank is of anangular cross-section when cut, and the pivotbar D thereof issubsequently diepressed into circular cross-section, while the ends Dare suitably finished to provide slightly-concaved beai'ingfaces, asshown in Figs. 6 and 9, it being noted that the connecting-plate D isstill disposed at one side of the longitudinal center of the bar, sothat when the lugs D are passed through the aptures A in the type-bar Aand secured therein in any desired manner-for instance, by heading, asshown in Fig. 9said type-bar will lie substantially in line with thelongitudinal center of the pivot-bar, while the bearings D at the endsof the pivot-bar D are seated into recesses or countersunk portions 0 ofthe journaling-screws C, said recesses being of greater depth than theportions D so as to allow an adjustment of the screws 0 into contactwith the bearing portions D without contacting with the extreme ends ofthe pivot-bar.

It will be seen that by forming this hangerbracket from sheet metal bystamping the same maybe made of much less weight than heretofore, whilethe pivot-lugs being formed with an aperture of continuously equaldiameter can be accurately drilled and the screws threaded therein, soas to produce the completed article with a minimum of handwork and atthe least cost of manufacture. It will also be observed that theimproved construction of pivot when used in connection with this bracketis adapted to be held in position by the adjusting-screws, and alldanger of jamming or wedging the bearing is obviated by the constructionof screw herein shown, while the connecting-plate of the type-barpresents an extended bearing-surface in connection therewith, so as tosecure the most desirable leverage and form of connection between thehanger and the type-bar carried thereby. The angular lugs entering therecesses of similar configuration in the bar prevent any possiblemovement of the parts upon each other.

It will be obvious that changes may be made in the details ofconstruction and configuration without departing from the spirit ofinvention as defined by the appended claims.

Having described my invention and set forth its merits, what I claim,and desire to secure by Letters Patent, is-
